casting at the upper front edge of the door. VV-ith'these objects in View the invention consists in the construction and arrangement of crank-arms and cams for cooperating with the front edge of the door to force the same inwardly to make a tight joint, said crankarms and catns being arranged within the lines of the thickness of the door; in the means for locking these crank-arms and cams in position; in the construction and arrangement of the cams; in the construction and arrangement of rods at the rear edge of the door; the rotary disk for operating said rods; the bandle for rotating said disk, which handle also acts as a lever to force the door inwardly and as a hasp to lock the door in position after it has been forced inwardly; in the construction and novel arrangements of the loop-fulcrum audits countersunk casing; and, finally, the invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described, and afterward pointed out in the claims.

In the drawings, A indicates the side wall of the car, to which is secured in any suitable manner an upper track B, whose front edge recedes toward the wall of the car.

0 indicates the lower track, which, as shown in Fig. 5, also recedes toward the wall of the car at its front edge. This track C is preferably inounted upon suitable supports 0, whose construction is more clearly shown in Figs. 39, 40, and 41, where it will be seen that the upper face is inclined to permit water to run off. The space between these supports is open to prevent the accumulation of water.

D indicates the cardoor,- which is con structed in any suitable manner, but preferably as shown in the drawings, in which it will be seen by reference to Figs. 1 to 5 that a suitable door-frameis provided, upon which frame is arranged an outer door-facing and an inner door-facing, between the facings being suitable packing. The inner door-facing is raised from the frame of the door, so as to make a rabbeted joint with the door-casing when the door is forced inwardly. Sealingstrips D are arranged around the inner facing of the door and are adapted to be forced against the outer faces of the door-casing on all four sides, so as to make a tight joint. By making these sealing-strips separate and removable it will be seen that they may be easily replaced by new strips when worn.

E indicates a post secured to the side wall of the car in juxtaposition to the front doorpost. E indicates a strip of metal secured to the outer edge of the post E, behind which strip the front edge of the door is forced in the act of closing it.

F, F, and F indicate, respectively, the upper, middle, and lower castings, which are arranged upon the front edge of the door. These castings are shown more clearly in detail in Figs. 17 to 27. Each of the castings is provided with a recess or pocket f, which opens to the front and outer faces of the door. The lowercasting F is provided with a roller f, with an extended bearing-surface, so as to permit it to he slid laterally over the lower track 0, with which it cooperates. For strength this lower casting extends around the rear face of the door, and in order to enable the strips D to be secured at their mitered joints to the door-frame I preferably cut away the rear wall of this lower casting, as shown at f.

f indicates an extension or fin on the upper casting, which extends behind the upper track B, and findicates an extension or fin on the lower casting, which extends behind the lower track 0.

G and G indicate, respectively, castings which are secured to the upper and lower edges at the rear end of the door. These castings have ways 9 on their edges for the reception of a sliding and adjustable eye H. This eye is made adjustable by a bolt (not shown) which passes through a slot formed in the base-plate of the eye and into an openingg in the castings. Arollergisarranged in the lower casting, and this casting also has a back plate extending behind the door, which is cut away to permit the passage of fasteners into the door-frame for the strips.

9' indicates an extension or fin on the upper casting, which extends behind the top track B, and g an extension or fin on the lower casting, which extends behind the lower track C.

I indicates a wear-plate countersunk into the rear edge of the door and provided with a shoulder t on its outer face. Mounted in this wear-plate is a rotary disk J, which consists, preferably, of two members connected by a web, between which members are pivoted rods K and K, extending behind the upper and lower tracks, respectively, said rods passing through the eyes H. The ends of these rods are inclined or formed with camfaees, as shown in Fig. 11, so that when the rods are forced up and down to cooperate with their respective tracks the cam-faces of the rods force the rear edge of the door inwardly.

L indicates a handle pivoted in cars extending from the rotary disk and to one side of the pivotal point of said disk, said handle being provided with a hooked portion Z at its inner end, while the outer end of the handle has a slot formed therein to cooperate with a staple on the car-door.

M indicates a bolt suspended by a chain from the car-door to cooperate with the staple and hasp to lock the latter in place. A suitable slot is formed in the lower end of the bolt, as is common, for the passage of the seal-wire.

N indicates a frame forming a recess or pocket and provided with a nosed portion a near one end, under which nose is placed a loop-fulcrum 0, adapted to be swung on said nose as a pivot.

The operation of these parts for'seeuring the rear edge of the door is as follows: The

door being closed, the handle L'is raised to IlO a horizontal position, which rotates the disk and forces the rods K and K behind their respective tracks. When the handle is in a horizontal position, the loop is swung outwardly and over the nose Z of the handle. The handle is now turned back against the side of the door, the lever-loop aetingas a fulcrum to force the center of the door inwardly. hen the handle is in a closed position, it is above the lug t' of the wearplate I, which holds the handle in position. The bolt M is now inserted through the staple and the seal attached, as is usual.

In order to give strength to the rotary disk, I preferably increase the metal on the periphery thereof, as at j, and these projections, or at least those projections nearest the side wall of the car, are used to force the door outwardly when the rods K and K are withdrawn. This. will be obvious by referring to Fig. 7, where the door appears as locked. When the handle is turned out at right angles to the door, its downward movement to withdraw the cam-faces on the ends of rods K and K will rotate the disk and forcethe inner projection against the side wall of the car, which will initially throw the door outwardly.

To add rigidity between the handle and disk when the door is locked, I form a lug or projectionj on the disk, as shown in Fig.8, which cooperates with a recess or pocket Z in the handle, as is obvious.

P indicates crank-arms mounted in the post E, the inner ends of which crank-arms have mounted upon them cams P, while the outer ends of the crank-arms have mounted upon them a rod Q, so that when said rod is operated the crank-arms and cams will be operated in unison. On one of the cams, preferably the lower, I form a squared shank,-outside of which projects a stud, as shown in Fig. 12, where it will be seen that 19 indicates the squared shank, and p the stud. R indicates a wrench mounted upon the stud and adapted to cooperate with said squared shank.

This wrench can be engaged with and disen- V gaged from the squared shank at the will of v the operator simply by moving it longitudias to hold the door tightly in place, I mount a pawl S on the rod Q, which pawl cooperates with a rack T, secured to the side of the car. It will readily be seen that as the rod Q moves on an arc of a circle described from the axis of the crank-arm-that is, inwardly and downwardlythis pawl will fall back by gravity under the teeth of the rack and lock the rod in place when it has completed its movement. In order to release the rod, it is only necessary to place the wrench in position and press the rod downwardly to free the pawl, which can be turned back out of engagement with the rack. The pawl can also be used to hold the cams in their raised position to permit the movement of the door in opening or closing, as shown by the dotted lines of Fig. 16.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
